Product Summary

Putlog coupler is a non-load-bearing coupler used in the erection of tubular scaffolding for fastening a transom or putlog to a ledger. A putlog is a short horizontal pole projecting from a wall, on which the floorboards of scaffolding rest. Scaffolding is a temporary structure used to support people and material in the construction or repair of buildings and other large structures. It is usually a modular system of metal pipes or tubes, although it can be made out of other materials. Putlog coupler is one of the basic materials of scaffoldings. The basic materials of scaffoldings are tubes, couplers and boards. Couplers are the fittings which hold the tubes together. The most common are called scaffold couplers. Putlog coupler is one type of scaffold coupler. To join tubes end-to-end joint pins (also called spigots) or sleeve couplers are used, or both together. Only right angle couplers and swivel couplers can be used to fix tube in a 'load-bearing connection'. Single couplers are not load-bearing couplers and have no design capacity.

Putlog couplers are essentially the fundamental component that is used to assemble tube-and-coupler scaffolding. Tube-and-coupler scaffolding is defined as 'a scaffold in which individual circular tubes serving as standards, braces or ties are joined together by means of purpose designed couplers'. This basic fitting that is designed to join two scaffold tubes can be used to create a diverse range of scaffolding structures or used as an accessory to prefabricated scaffolding systems. Putlog couplers are used for fixing putlog tubes onto ledger tubes. They are typically used for securing guardrails and mid rails at right angles to standards.
